This invention relates to a new and useful improvement in dump-cars ofthat class commonly known as inwardly tilting sections---to wit, wherethe containingI sections are so mounted that they discharge their loadby being dumped toward each other.

The objects of my present invention are to improve generally upon thistype of dumpcar, particularly with respect to making' the parts rigidand strong, so as to enable the car to stand up in the rough service towhich it is subiected.

lYith these objects in view the invention consists in the construction,arrangement, and combination of the several parts, all as will behereinafter described and afterward pointed out in the claims.

frame comprising the usual end sills 1 and side sills Q, the latterbeing' shown as pressedsteel side sills; but it isnobvlous that the sideg sills can be built up of plates and angles, as is well known in thisart.

3 indicates the bolster, which ot' wellknown form.

The draft-sills 6 extend between the end sill and web of the bolster andin addition obliquely-arranged braces or diagonals T may be employed, asdesired. Short sills continue inwardly beyond the bolster to which theyare secured, said sills being also connected to a cross member 9.Diagonal braces 9 may he used to stiifen the member 9.

The side frame ot' the car is a trussed structure, ot' which the angle 5and the side sills 2 form constituent elements --to wit, the top andbottom chords, respectively-the angles 4 `forming posts opposite thebolster-points, as will readily be seen. Posts l0 are secured to theside sills and through suit-able connection-plates to the ang'le 5 atpoints intermediate the bolster and in vertical alinement with thebearings 11 for the trunnions or pivotal supports of the tiltingsections. Diagonals 12 are also provided, the same diverging from theconnection-plates at the upper ends ot' the posts 10, their lower endsbeing riveted to the side sills.

13 indicates a medial 'flanged plate which is riveted to the side silland to the angle A flanged plate 13 is secured to and extends above saidangle and carries at its upper end a connecting' tie member 11, whichmay be made ot' flanged metal. A corner-gusset 13 is employed tostrengthen the member 11 at its ends, in addition to which braces 11 maybe used at points between the ends. Riveted to plate 123 is aninwardly-extemling gussetplate 15, which is located in the space betweenthe inwardly-tilting sections when the same are dumped, as shown bydotted lines in Eig. 1. Connecting-angles 15 are employed to secure thegusset-plate to the plate 13, as shown in Fig. 1". The dumping-sectionsare composed of side walls 16, which are preferably tormed withinwardly-extcnding embossments 1T for the purpose of adding strength andrigidity to the structure. In addition to these em bossmentsstillening-angles may also be riveted to these side plates to resistbulging' tendencies. Each tilting' section is pre1- ln the drawings lhave illustrated an under.- l erably provided with an outer end wall 18and IOO a iioor 19, the latter being embossed and provided with raisedribs 20, which are preferably longitudinally disposed to add strength tothe structure, in addition to which transversely-arranged angles 21 maybe riveted under the floor for well-understood purposes. The floor-sheetis preferably flanged at its sides, or a connection-angle may beemployed to rivet it to the side and end walls. A bulbangle 22 isriveted around the upper edges of the side and end walls, said anglehaving its beaded leg extendinginwardly. The inner end wall 23 connectsthe side walls and is embossed at 23L to give it strength.

In the construction shown in Figs. 1 and 13 the side walls have rivetedto them strikers or stops 16, which cooperate with the side sills 2 whenthe sections are dumped. These side walls are also provided withsuitable cast trunnions 24, provided with theusual attaching-flanges andstrengthening-ribs for well-known purposes. These trunnions have collars25 arranged on each side of the bearing 11, so as to prevent lateraldisplacement of the trunnion in its bearing. In addition to this thetrunnions are made hollow for the passage of a tie-rod 26, said tie-rodbeing threaded at its end and provided with jamnuts. Between thecastings 24 is arranged an angle 27, under which the tie-rod isarranged, said angle having its ends seated in the castings 24 andacting as a distance-piece to prevent the tilting section from gettingout of alinement at its bearing-points.

Instead of employing a rolled channel 10 as a supporting-post for thebearing 11, said channel being shown in Figs. 1 and 13, I may use a castpost 10u (shown in Fig. 14) and a spacing-pipe 27h, surrounding the rod26. Instead of mounting trunnions on the tilting section I may employ ajournal-support for said sections, as illustrated in Fig. 15, in whichthe journal 11L is mounted in the upper end of the post and the casting24a is riveted to the side wall of the tilting section and is looselymounted on said journal. Instead of using an angle or spacing sleevecollars 27 may be rigidly secured to the journal, which journal may bemade hollow and a tie-bolt 26a used in connection therewith, asheretofore described.

In order to prevent the tilting sections from accidentally dumping, Ipreferably rivet keeper-plates 28 to the side walls thereof, whichkeeper-plates (see Figs. 7 and 10) cooperate with spring-pressedlatch-bolts 29, passing through the side sills and mounted in suitablebearings, as shown. The outer endsv of these latch-bolts are pivotal-lyconnected to levers 30, fulcrumed in lugs 31, mounted on the side sills,the inner ends of said levers being provided with pins or rollerscoperating in the grooves of a cam 32. This cam is formed with a lockingprojection 33, with which coperate locking-pawls 34. Cam 32 is mountedon a shaft 35, which preferably extends from side to side of the car,(the latch mechanism herein shown being duplicated on each side of thecar, but the locking mechanism being preferably placed on one side ofthe car only,) one end of the shaft-the one on which the cam 32 ismounted-being provided with a non-circular portion for the reception ofa socket-Wrench, whereby the shaft may be rotated. Upon rotating theshaft all of the latches 29 are withdrawn and the tilting sections arepermitted to descend. When the tilting sections return to normalposition, their keeper-plates pass above the latches, the spring behindthe latches forcing them under the keeperplates, so as to hold thetilting sections home.

To avoid the chaing of the tilting sections i against the side sill inmoving to and from their dumping positions, I mount chaingplates 36 onthe side sill, as shown in Figs. 1 and l1, or an antifriction-roller 36may be mounted on the side sill, as shown in Fig. 12.

Referring now to Figs. 1 and 4, it will be seen that the upper `inneredges of the side walls of each of the tilting sections are curved on anarc of a circle described from the pivotal point of said tiltingsections. The lower inner edges are straight and cooperate with across-ridge comprising plates 37, which are riveted to the side sillsand reinforced by stilfening-angles 38 and saddle -plates 37. Thiscross-ridge forms a Very rigid connection between the side frames at themiddle of the car and enables me to dispense with the use of centersills and support the tilting sections on the side frames thus rigidlyconnected. The flanged plate 14 also serves as an effectual tie, and thegusset-plates extending up on each side of the cross-ridge, to whichthey are connected, and to the trussed side frames effectually stifi'enthe structure. It is intended that there shall be sufficient clearanceof the framing of the car to permit the tilting sections to move freelyWithout friction, said tilting sections being held in their normalposition principally by their supporting-trunnions, part of the weightbeing received by the extensions 39, extending up from the underframe,and by the latches.

In Figs. 3 and 4 I have shown a mechanism for positively moving thesections to and from their open positions. This is useful in connectionwith my improved construction, particularly in cold weather where waterfrom rain or snow freezes, so as to prevent the free movement of theparts and the ready discharge of the load. This mechanism is capable ofbeing operated by hand or compressed air. The construction comprises ashaft 42, having the usual squared stem for attachment of asocket-Wrench. 43 indicates a worm-wheel on the inner end of this shaft,which cooperates with a worm-Wheel 44, fixed to a shaft 45. On shaft 45is a bell-crank IOO IIO

lever 46, carrying a swivel connection et?, in which are mounted links8, connected by ball-and-socket lioints to the tilt-ing sections,respectively. 'lhe other member ot the bellcrank lever 4:6 is connectedby a link it) to a fluid-actuated piston arranged in a cylinder 5l).\Vhen shat't 4Q is rotated manually, the sections are raised or loweredand the piston is idly reciprocated, and when pressure is admittedbehind the piston the sections are lowered, shaft 492 rotating idly,pressure in t'ront ot' the pistons returning the sections home. lhannels51, carried by the side sills, support the moving parts ot' thesection-operating mechanism, as well as the cylinder 50.

l am aware that minor changes in the construction, arrangement, andcombination ot' the several parts ot' my device can be made andsubstituted for those herein shown and described without in the leastdepartingfroi'n the nature and principle of my invention.
